java - Axis2网络服务: wrong number of arguments when invoking method

Question

我正在尝试使用 axis2 设置网络服务。我在 Eclipse 下创建了一个 Dynamic Web Projet，使用 Apache Tomcat 7 和动态 Web 版本 2.5。我已将 Axis 2 Facets 添加到配置中。

我有以下类(class):

package com.jo.ws;

public class Test {
    public int add(int a, int b) {
        return a + b;
    }
}

然后，我使用自下而上的 Java bean Web 服务为该项目创建了一个 WebService，并将我的 Test 类添加到服务实现中。我在 slider 中选择了“启动服务”，并将配置中的 Apache Axis 更改为 Axis 2。然后，我使用默认选项生成了默认的 services.xml 文件。

我可以通过以下地址在网上访问我的项目:

http://localhost:8888/Axis2WS/

这将显示 Axis 2 页面，我可以看到我的服务处于 Activity 状态

 http://localhost:8888/Axis2WS/services/listServices 

wsdl 已正确生成并显示

如果需要的话我可以发布它。

但现在如果我这样做:

http://localhost:8888/Axis2WS/services/Test?method=add&a=2&b=1

我明白了:

<soapenv:Reason xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
<soapenv:Text xml:lang="en-US">wrong number of arguments</soapenv:Text>
</soapenv:Reason>

我还在 Eclipse 控制台日志中收到错误，并显示以下堆栈跟踪:

知道我做错了什么吗？

感谢您的帮助!

错误来 self 在浏览器中输入的网址。调用该方法的正确 URL 是:

http://localhost:8888/Axis2WS/services/Test/add?a=3&b=2

您需要替换“？”在方法名称前加上“/”，然后在添加“？”后写入参数。在你的方法名称之后
